PRINCIPLE

What does it measure?

Chronotype reflects your circadian timing preference driven by biological rhythms and environmental cues. Reports include sleep midpoint, melatonin timing, and schedule fit.

Morning Lark
Early sleep/wake preference; best performance in early hours; light exposure in morning helps.
Night Owl
Late sleep/wake preference; peak productivity in evening; reduce blue light at night.
Intermediate
Flexible schedule fit; balanced performance across the day; adapt with consistent routines.
Sleep Midpoint
Useful indicator of circadian timing; combined with wake preference to profile chronotype.
Social Jetlag
Misalignment between biological clock and social schedule; reduce with consistent sleep window.
Clinical Caution
Not a diagnosis. For suspected DSPD/ASPD or insomnia, consult a licensed clinician.
